Dr. O'Dowd is a 1940 British drama film directed by Herbert Mason, produced by Sam Sax for Warner Bros and starring Shaun Glenville, Peggy Cummins, Felix Aylmer and Irene Handl. Set in Ireland, it focuses on Marius O'Dowd, an Irish doctor, who works to restore his relationship with his son after his daughter-in-law dies under O'Dowd's care. The film was the onscreen debut for Peggy Cummins, who was only thirteen at the time. It was well received by critics, and Cummins' role was the subject of particular praise. The film is currently missing from the BFI National Archive, and is listed as one of the British Film Institute's "75 Most Wanted" lost films. Plot Marius O'Dowd (Shaun Glenville) is an Irish doctor who is often drunk. His daughter-in-law Moira (Pamela Wood) dies during a serious operation which O'Dowd is performing. Although O'Dowd is not to blame, his son Stephen (Liam Gaffney) suspects that Moira died due to O'Dowd operating while under the influence of alcohol, and accuses him of criminal neglect. O'Dowd consequently has his license to practice medicine taken away. Stephen also does not tell his daughter Pat (Peggy Cummins) that Marius is her grandfather, although several years later she becomes friends with Marius and works this out. Marius eventually manages to redeem himself by saving Stephen's life during an outbreak of diphtheria.
